$y=f(x)\\\\g(x)=f(x+7)-1$

Example:

$f(x)=x^2+3\\\\g(x)=f(x+7)-1=(x+7)^2+3-1=x^2+14x+49+2=x^2+14x+51$

The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is , where l represents t

Gekata [30.6K]

Answer:

A. 7 in.

Step-by-step explanation:

We have been given that the perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is , where l represents the length of the rectangle and w represents the width of the rectangle.

We know that perimeter of rectangle is 2 times the sum of width and length of rectangle.

$\text{Perimeter}=2(l+w)$

$\text{16 in}=2(l+w)$

$\frac{\text{16 in}}{2}=\frac{2(l+w)}{2}$

$\text{8 in}=l+w$

To be a rectangle length cannot be 8 as length and width of the rectangle is 8 inches.

Therefore, 7 inches the possible value for the length of the rectangle.

What is the factored form of 8x2 + 12x? 4(4x2 + 8x) 4x(2x + 3) 8x(x + 4) 8x(x2 + 4)

earnstyle [38]

So I'm guessing that the x2 is your way of saying 2 is the exponent right? In that case the equation would be 8x^2 + 12x
Well you would have to pull out the gcf which in this case will be 4x after pulling out the gcf you should get 4x(2x + 3)
